Building Description: 75-story steel-reinforced concrete skyscraper
Problem: The building is in danger of collapsing from poor design
Task: Recommend a new structural design
Budget: $500 million


Special Notes: "This is going to be a state-of-the-art building. We're planning to have 100 deluxe apartments, two swimming pools, 50 shops, and one movie theater in this skyscraper. We want lots of open space and large, unobstructed windows on each floor. Can you do this for us?"
-- Building Owners

The pressure is on. You want to make the owners of the skyscraper happy, but you also have to decide which design is strong enough to support the tall and heavy structure.
